Abstract
Composés de formule (I) dans laquelle X représente CH ou N; n est égal à 0, 1, 2 ou 3; R1 et R3, qui peuvent être identiques ou différents, représentent un alkyle, un alkoxy ou un alkylthio, dont chacun est éventuellement substitué, un halogène, un nitro, un cyano, COOR4, -NR5R6, CONR5R6, COR7 ou R8S(O)q; ou bien R1 ainsi qu'un groupe R3 adjacent, ou deux groupes R3 adjacents, conjointement avec les atomes de carbone auxquels ils sont liés, peuvent former un cycle ayant de 5 à 8 chaînons pouvant comprendre 1 à 3 hétéroatomes pouvant être substitués; R2 est un radical d'hydrocarbone aliphatique éventuellement substitué, qui peut être insaturé, un aryle ou un hétérocyclyle; R4 représente l'hydrogène ou un groupe formant un ether; R5 et R6 sont identiques ou différents et représentent un alkyle, un acyle ou bien un aryle éventuellement substitué, ou conjointement avec l'azote auquel ils sont liés, forment un cycle de 5 à 7 chaînons qui peut contenir d'autres hétéroatomes; R7 représente l'hydrogène, un alkyle ou un aryle éventuellement substitué; R8 représente un alkyle ou un aryle éventuellement substitué; et q est égal à 1 ou 2. Lesdits composés présentent une activité fongicide tout comme les intermédiaires de formule (II) dans laquelle R9 représente l'hydrogène ou le méthyle, et de formule III.Compounds of formula (I) in which X represents CH or N; n is 0, 1, 2 or 3; R1 and R3, which may be the same or different, represent an alkyl, an alkoxy or an alkylthio, each of which is optionally substituted, a halogen, a nitro, a cyano, COOR4, -NR5R6, CONR5R6, COR7 or R8S (O) q ; or R1 and an adjacent R3 group, or two adjacent R3 groups, together with the carbon atoms to which they are attached, can form a ring having 5 to 8 members, which may include 1 to 3 heteroatoms which may be substituted; R2 is an optionally substituted aliphatic hydrocarbon radical, which may be unsaturated, an aryl or a heterocyclyl; R4 represents hydrogen or an ether group; R5 and R6 are the same or different and represent an optionally substituted alkyl, acyl or aryl, or together with the nitrogen to which they are linked, form a 5 to 7-membered ring which may contain other heteroatoms; R7 represents hydrogen, optionally substituted alkyl or aryl; R8 represents optionally substituted alkyl or aryl; and q is equal to 1 or 2. Said compounds exhibit fungicidal activity just like the intermediates of formula (II) in which R9 represents hydrogen or methyl, and of formula III.
